ATTACHMENT FOR PUMP-RODS.

SPECIFICATION forming part of Letters Patent No. 649,882, dated May 15, 1900.

Application liled September lJ 1899. Serial No. 729,191. (No model.)

To @ZZ whom t may concern:

Beit known that I, ROYAL P. WEED, a citizen of the United States of America, residing at Lanark, in the county of Carroll and State of Illinois, have invented certain new and useful Improvements in Attachments for Pump- Rods, of which the following is aspecication.

My invention relates to certain improvements in attachments for pump-rods, the object of which is to relieve the pump and the driving mechanism from the great strain caused by the effort to start the column of water upon the upstroke. It is particularly valuable in connection with windmills and has been used most extensively for that purpose.

The drawings illustrate the preferred construction, showing a side elevation in Figure l, a central vertical section in line 2 2 of Fig. 1 in Fig. 2, a similar section at right angles thereto in Fig. 3, a horizontal section looking downward from the line et 4t of Fig. l in Fig. 4, a similar section in line 5 5 of the same figure in Fig. 5, a side elevation of the detail in Fig. 6, and a similar elevation of a part thereof in Fig. '7.

In the drawings, A is the Wind mill-rod, and

.B the pump-rod. The pump-rod is provided with a downward extension C, composed of two parts o c', secured upon opposite sides of the windmill-rod by means of bolts c2 c3 and extending below7 the rod in the form of a yoke c4, terminating at the bottom in a horizontal disk-shaped plate c5, formed by the union of the two parts c c' by means of bolts c o7. In this housing is arranged a coiled spring D, its lower end resting upon the plate c5, and a sliding block E is guided vertically at its upper end e in a socket c9 and extends at its lower end through an opening o8 in the diskshaped plate c5. A projecting ear or rib e rests upon the top of the spring D, and a similar rib e2 acts as a stop to check the downward movement of the block in the yoke by striking against the disk-shaped plate c5. The block E is made in the shape of a trough bridged at the bottom e3 to receive the pumprod B. A pin e4 is let into the block to engage the pump-rod, said pin being forced inward by a liat spring e5, secured to the block at e". The block is provided with a socket e7 and a perforated ear es, furnishing a bearing for a key, having a spindle f fitted to the ear and bearing a Wing f', arranged behind the spring, and a handle f2, in convenient position for manipulation. By drawing the handle forward in Fig. 6 the spring is lifted to withdraw the coupling-pin e4 from the pump-rod. A rivet e9 furnishes a stop to limit the movements of the key in this direction, sufiicient movement being permitted to enable the wing to swing past the dead-center, so as to lock the spring in an open position.

I do not limit myself to the exact construeL tion herein shown and described, as considerable variation is possible Without departing from the principle of the invention.

I claim as new and desire to secure by Letters Patent-n 1. The combination with the yoke, C, made up of the two pieces, c, o', adapted to be attached to opposite sides of the windmill-rod and terminating at the bottom in a diskshaped plate, c5, formed by securing the two pieces together at o, c7, of the trough-shaped block, E, guided in the yoke and provided with a shoulder and the spring', D, interposed between the disk-shaped plate and said shoulder; substantially as described.

2. The combination with the yoke, C, of the spring, D, supported therein, the block, E, guided in the yoke and bearing the ribs, e', c2, the former resting upon the top of the spring and the latter arranged to engage the yoke and limit the movement of the block with respect thereto; substantially as described.

In witness whereof I have hereunto set my hand, at Lanark, in the county of Carroll and State of Illinois, this 15th day of August, A. D.
